[0046] Please refer to Figure 1-Figure 7 This embodiment provides a proximal humeral fracture plate implantation guide 200, which includes a main frame 210, a sliding frame 220, a first Kirschner wire group 230, a second Kirschner wire group 240 and a third Kirschner wire group 250;

[0047] The sliding frame 220 is slidably connected to the main frame 210; the first Kirschner wire set 230 is detachably connected to the main frame 210 and is located at the top of the main frame 210; the second Kirschner wire set 240 and the third Kirschner wire set 250 are both detachably connected to the sliding frame 220;

[0048] Among them, the main frame 210 is used to be set parallel to the humerus 10; the first Kirschner wire group 230 is used to connect with the humeral head 11, and the first Kirschner wire group 230 is parallel to the fracture line direction of the humeral head 11; the second Kirschner wire group 240 and the third Kirschner wire group 250 are respectively connected to the greater tubercle 12 and the lesser tubercle 13 of the humerus 10.

[0049] Please refer to Figure 1-Figure 7 The working principle of the proximal humeral fracture plate implantation guide 200 is:

[0050] The proximal humeral fracture plate implantation guide 200 comprises a main frame body 210, a sliding frame 220, a first Kirschner wire group 230, a second Kirschner wire group 240 and a third Kirschner wire group 250; wherein the first Kirschner wire group 230 is used to connect with the humeral head 11, and the first Kirschner wire group 230 is parallel to the fracture line direction of the humeral head 11; the second Kirschner wire group 240 and the third Kirschner wire group 250 are respectively connected with the greater tubercle 12 and the lesser tubercle 13 of the humerus 10; and the main frame body 210 is used to be arranged in parallel with the humerus 10; therefore, when the proximal humeral fracture plate implantation guide 200 is used to reposition the humerus 10, the humeral head 11, the second Kirschner wire group 240 and the third Kirschner wire group 250 at the proximal fracture of the humerus 10 can be repositioned through the above contents. The greater tuberosity 12 and the lesser tuberosity 13 are positioned, and in the positioning process, the main frame body 210 is set parallel to the humerus 10 as a positioning reference, so as to determine the relative positions of the first Kirschner wire group 230, the second Kirschner wire group 240 and the third Kirschner wire group 250; and when the first Kirschner wire group 230 is installed, the first Kirschner wire group 230 is parallel to the fracture line direction of the humeral head 11, so that the neck-shaft angle of the humerus 10 can be reduced by such a setting; and when the second Kirschner wire group 240 and the third Kirschner wire group 250 are installed, the sliding frame 220 can also be slid relative to the main frame body 210 to adjust its position to meet the needs of reducing the humerus 10;

[0051] In summary, the proximal humeral fracture plate implantation guide 200 can reduce the difficulty of reduction during the reduction of the proximal humeral fracture 10 and avoid secondary displacement during the operation, thereby simplifying the operation and improving the reduction efficiency.

[0052] For further information, please refer to Figure 1-Figure 7 In this embodiment, the proximal humeral fracture plate implantation guide 200 further includes a retaining rod 260 ; the retaining rod 260 is detachably connected to the main frame body 210 and is parallel to the forearm 20 connected to the humerus 10 .

[0053] Thus, through such a setting, after the installation between the first Kirschner wire group 230, the second Kirschner wire group 240 and the third Kirschner wire group 250 is completed, that is, after the humeral head 11 is relatively fixed with the greater tubercle 12 or the lesser tubercle 13, under the premise that the main frame 210 is arranged parallel to the humerus 10, the position of the forearm 20 can be determined by setting the retaining rod 260, that is, the forearm 20 is made parallel to the retaining rod 260, thereby completing the reduction of the posterior tilt angle of the humerus 10. It should be noted that when installing the retaining rod 260, the doctor needs to determine the angle required for the retaining rod 260, that is, the angle between the retaining rod 260 and the main frame 210 needs to be adjusted according to the actual situation.

[0054] In order to facilitate the installation of the retaining rod 260 and the adjustment of the angle of the retaining rod 260, a connecting column 211 is provided at one end of the main frame 210 away from the first Kirschner wire group 230, and the connecting column 211 extends along the center line direction of the main frame 210; and a plurality of connecting holes 212 are provided on the connecting column 211, and the retaining rod 260 is connected to one of the connecting holes 212.

[0055] Therefore, when installing the retaining rod 260, the doctor can determine the required angle of the retaining rod 260, that is, the doctor can connect the retaining rod 260 to different connecting holes 212 according to actual conditions, so that the angle between the retaining rod 260 and the main frame 210 can be changed between 20°, 30° or 40°.

[0056] When arranging the above-mentioned multiple connecting holes 212, in order to enable the angle of the retaining rod 260 to the main frame 210 to be changed between 20°, 30° or 40°, the multiple connecting holes 212 are arranged at intervals around the axis of the connecting column 211 and distributed at intervals along the axis of the connecting column 211.

[0057] For further information, please refer to Figure 1-Figure 7Based on the above content, in the present embodiment, when the first K-wire group 230 is set, the first K-wire group 230 includes at least one first K-wire 231 and at least one first sleeve 232; the first K-wire 231 corresponds to the first sleeve 232 one by one, and each first sleeve 232 is sleeved on the corresponding first K-wire 231; the first sleeve 232 is detachably connected to the main frame 210.

[0058] In order to install the above-mentioned first sleeve 232, the main frame 210 is provided with at least one first mounting groove 213; each first mounting groove 213 is used for allowing the first Kirschner wire 231 to pass through, and each first mounting groove 213 is used to detachably cooperate with a first sleeve 232; wherein, when the first sleeve 232 cooperates with the first mounting groove 213, the first Kirschner wire 231 in the first sleeve 232 is arranged at an angle to the main frame 210. It should be noted that when the first Kirschner wire 231 in the first sleeve 232 is set at an angle with the main frame body 210, the purpose is to set the first Kirschner wire 231 in the first sleeve 232 at an angle of 50° with the main frame body 210. The reason is: since the main frame body 210 is set parallel to the humerus 10, and the first Kirschner wire group 230 is parallel to the fracture line direction of the humeral head 11, the first Kirschner wire 231 set at an angle with the main frame body 210 can be used to adapt to the fixed angle of 50° between the humeral head 11 and the shaft of the humerus 10, thereby restoring the neck-shaft angle.

[0059] In summary, please refer to Figure 1-Figure 7 Based on the above content, in this embodiment, when the first Kirschner wire set 230 is set, the first Kirschner wire set 230 includes two first Kirschner wires 231 and two first sleeves 232, and the main frame 210 is provided with two first mounting grooves 213; the two first sleeves 232 are respectively sleeved on the two first Kirschner wires 231, and respectively cooperate with the two first mounting grooves 213. Thus, through such a setting, the stability during use is improved, thereby avoiding the problem of secondary displacement during the reduction process.

[0060] Further, in the present embodiment, when the second K-wire set 240 is provided, the second K-wire set 240 includes at least one second K-wire 241 and at least one second sleeve 242; the second K-wire 241 corresponds to the second sleeve 242 one by one, and each second sleeve 242 is sleeved on the corresponding second K-wire 241; the second sleeve 242 is detachably connected to the sliding frame 220;

[0061] When setting the third K-wire group 250, the third K-wire group 250 includes at least one third K-wire 251 and at least one third sleeve 252; the third K-wires 251 correspond to the third sleeves 252 one by one, and each third sleeve 252 is sleeved on the corresponding third K-wire 251; the third sleeve 252 is detachably connected to the sliding frame 220.

[0062] Furthermore, the sliding frame 220 is provided with at least one second mounting groove 221 and at least one third mounting groove 222; the second sleeve 242 is detachably matched with the second mounting groove 221, and the third sleeve 252 is detachably matched with the third mounting groove 222. Moreover, the second mounting groove 221 and the third mounting groove 222 are relatively located on two sides of the main frame body 210.

[0063] In summary, please refer to Figure 1-Figure 7 Based on the above, in this embodiment, when the second Kirschner wire group 240 and the third Kirschner wire group 250 are set, the second Kirschner wire group 240 includes two second Kirschner wires 241 and two second sleeves 242, and the third Kirschner wire group 250 includes two third Kirschner wires 251 and two third sleeves 252, and the sliding frame 220 is provided with two second mounting grooves 221 and two third mounting grooves 222; the two second sleeves 242 are respectively sleeved on the two second Kirschner wires 241, and respectively cooperate with the two second mounting grooves 221; the two third sleeves 252 are respectively sleeved on the two third Kirschner wires 251, and respectively cooperate with the two third mounting grooves 222. Thus, by such a setting method, the stability during use is improved, thereby avoiding the problem of secondary displacement during the reduction process.

[0064] For further information, please refer to Figure 1-Figure 7 In this embodiment, when the sliding frame 220 is installed, the sliding frame 220 is slidably connected to the main frame body 210 along the extension direction of the main frame body 210, and the purpose of slidably connecting the sliding frame 220 is to adjust the positions of the second Kirschner wire group 240 and the third Kirschner wire group 250. Therefore, in order to make the sliding frame 220 slidably connected to the main frame body 210, the proximal humeral fracture plate implantation guide 200 also includes a locking member 271 and a locking rod 272;

[0065] The main frame 210 is provided with a slide groove 214 and a locking groove 215, both of which extend along the center line direction of the main frame 210; the sliding frame 220 is slidably matched with the slide groove 214; the locking member 271 is rotatably connected with the sliding frame 220; the locking rod 272 is slidably matched with the locking groove 215, and the locking member 271 is threadedly connected with the locking rod 272;

[0066] The locking member 271 is used to rotate under the action of external force, so that the locking rod 272 is pressed against the locking groove 215 , thereby limiting the sliding of the sliding frame 220 relative to the sliding groove 214 .

[0067] Based on the above, please refer to Figure 1-Figure 7 The steps of applying the proximal humeral fracture plate implantation guide 200 to fracture reduction during surgery are as follows:

[0068] Please refer to Figure 5 , and combined with Figure 1-Figure 4 , the humeral head 11 is cut open to expose it, and one to two first Kirschner wires 231 are inserted into the humeral head 11 in a direction parallel to the fracture line of the humeral head 11, so that the first Kirschner wires 231 pass through the first mounting groove 213 at the upper end of the main frame 210, and then the tail of the first Kirschner wire 231 is inserted into the first sleeve 232 until the first sleeve 232 is inserted into the first mounting groove 213 at the upper end of the main frame 210, that is, the neck-shaft angle of the humerus 10 is reduced;

[0069] Please refer to Figure 7 , and combined with Figure 1-Figure 6 , reposition the greater tuberosity 12 and the lesser tuberosity 13, insert 1 to 2 second Kirschner wires 241 and the third Kirschner wire 251 into the greater tuberosity 12 and the lesser tuberosity 13 respectively, after the greater tuberosity 12 and the lesser tuberosity 13 are relatively fixed to the humeral head 11, the tail of the second Kirschner wire 241 is inserted into the second sleeve 242, and the tail of the third Kirschner wire 251 is inserted into the third sleeve 252, until the second sleeve 242 and the third sleeve 252 are inserted into the second mounting groove 221 and the third mounting groove 222 on the sliding frame 220; it should be noted that when installing the second sleeve 242 and the third sleeve 252, it is necessary to pre-adjust the position of the sliding frame 220 relative to the main frame body 210, and then rotate the locking member 271 to lock the sliding frame 220 to the main frame body 210;

[0070] Please refer to Figure 6 , and combined with Figure 1-Figure 5 After the humeral head 11 and the greater tuberosity 12 are relatively fixed, the position of the main frame 210 is adjusted so that the main frame 210 is parallel to the humeral shaft 10, and at the same time, a retaining rod 260 is inserted into a connecting hole 212 on the connecting column 211 (the multiple connecting holes 212 have three options of 20°, 30°, and 40°, and the doctor determines the required angle). At this time, the elbow is flexed 90° to make the forearm 20 parallel to the retaining rod 260, and the posterior tilt angle of the humerus 10 is restored;

[0071] In summary, please refer to Figure 7 , and combined with Figure 1-Figure 6At this time, the humeral head 11, the greater tuberosity 12, the lesser tuberosity 13 and the humeral shaft 10 have been relatively restored; keep the upper arm still, remove the first sleeve 232, the second sleeve 242, the third sleeve 252 and the main frame 210, and then proceed with the steel plate 30 implantation step; it should be noted that when removing the main frame 210, the first sleeve 232, the second sleeve 242, and the third sleeve 252 are withdrawn along the notches of the first mounting groove 213, the second mounting groove 221 and the third mounting groove 222, and the Kirschner wire is retained.
